OK.
Firefighting 101.
Drywall does not burn. Fire travels inside walls(studs do burn). To put a fire out you must "open" the wall/ceiling, that is where the axe come to use. After the fire is out, you do "overhaul" - making sure that the fire did not spread and is not somewhere in the dormant/backdraft stage.
In this case, fire was inside the ceiling, and that hole was not burned, but cut(drywall ripped down), and fire was put out.
Fire started in the kitchen, and burned it's way into the bathroom above, and bedroom beside bathroom.
Give me a few, and I'll post few more pics...
